ABC late-night comic Jimmy Kimmel is trying to de-escalate a fight with Fox News host Sean Hannity that began over a joke about first lady Melania Trump’s accent.

Kimmel says in a Twitter post made Sunday his exchanges with Hannity have been enjoyable however he doesn’t wish to add to the “vitriol” of their spat. He says such bitterness is “harmful to our country.”

On Jimmy Kimmel Live April 2, Kimmel prodded the very first lady’s reading of a children’s book at the White Home Easter egg hunt. He buffooned the accent of the first lady, who was born in Slovenia.

Hannity took exception. The two exchanged barbs through the week.

Kimmel states he hopes Hannity will “continue his newly-found advocacy for ladies, immigrants and First Ladies.”
